VHF Radio

Just wondering if you've tried using the tracking feature because on page 87 of my manual it says:  "The HX870 allows you to set 1-15 waypoints along a route"

I haven't tried setting up a route, but it seems to me that Standard Horizon is saying we're limited to 15 waypoints along any single route.  Maybe I'll try it and see.

"If it tells you what direction to go, that's pretty cool."

Lee, When I set a course using my HX870 to return to a waypoint, the radio shows me distance to point and direction continuously as I head for it. Testing this  with a highly identifiable location (launch site) the radio says I've "arrived" when I'm within a couple hundred yards of the point. I am assuming this means it isn't an extremely precise GPS unit. However, it has been nice, being 5 miles off shore with strong tide current and wind and know that even if I couldn't see marks I could get back close to my starting point. If someone knows how to make better use of this, I'd love to hear it. Thanks!
